Overall the girls have been sleeping wonderfully at night, and naps are getting better. I have not had to go in either of their rooms in the middle of the night for about a week now. We were going to put Hannah back in the nursery last night, but she is trying to pull up on everything now, so we really needed to drop the cribs down first. Since Matt did that today, (and Hannah immediately pulled up when we tested it out), the girls are back together tonight. We will see how it goes.
I think I will still leave the pack n play up for the occasions when one of them cries inconsolably at night and for naps, which need to be a little longer preferably and I do not want one waking the other. But maybe they will do ok in the same room again. We need to make the other room a play room and not a second bedroom!
At least now I can turn off the cheap monitor we had to buy for the second room. The static is so loud! Now I know why we got the digital monitor in the first place. :)
